We just sailed the Western Caribbean May 2013 and got a day pass for the Westin Grand Cayman on Seven Mile beach for $156 for the day (this was the total for 4 of us, so worked out to $39 per person - includes all taxes, resort charge and service charges) and loved it! It included a room, use of pool and access to a beautiful stretch of the beach. One of the staff set up 4 chairs with towels and an umbrella for us. There is a security box in the room you can use to store any valuables while enjoying the beach. They have snorkel equipment and other beach water activities for an extra fee. We were able to get a taxi from the port directly to the Westin. Try and get off the ship and into a taxi as soon as you can so you have the full day to enjoy your day at the beach. We didn't book ahead, just showed up, but would recommend booking ahead of time to guarantee your day pass.
